STARTER CIRCUIT
Battery voltage is applied to terminal "B" of starter solenoid at all times. (Scheme 17) When the ignition is turned to START position, battery voltage is sent through either a clutch pedal position switch (M/T) or transmission range switch (A/T) to terminal "S" of starter solenoid. This energizes the solenoid, applying voltage to starter motor, engaging starter drive gear to flywheel and cranking engine.
PINION GAP
| CAUTION | DO NOT apply voltage to starter assembly for more than 10 seconds. |
- With starter on a bench, disconnect terminal connector from starter solenoid "M" terminal. (Scheme 17)
- Apply battery voltage to solenoid "S" terminal and ground starter motor body. Pinion will eject.
- Measure pinion gap between pinion and stopper. See «STARTER SPECIFICATIONS.»(ref-164133-S08064517602004072200000) (Scheme 18)
- If pinion gap is not within specification, make adjustment by increasing or decreasing number of washers between solenoid and drive housing. Gap will decrease as number of washers is increased. Do not use more washers than plates. (Scheme 19)

TRANSAXLE RANGE SWITCH (A/T MODELS)
Note. Verify that the starter operates only with ignition switch in START position and selector lever in "P" or "N" position. The back-up lights illuminate when shifted to "R" position with ignition switch in ON position.
Note. Verify that the position of selector lever and shift pattern indicator of instrument cluster correspond. If not as specified, check the transaxle range switch.
- Disconnect negative battery cable.
- Disconnect transaxle range switch connector. (Scheme 20)
- Check for continuity at transaxle range switch as illustrated. (Scheme 21)
- If not as specified, replace or adjust transaxle range switch.
- Connect transaxle range switch connector.
- Connect negative battery cable.

WILL NOT CRANK-STARTER MOTOR DOES NOT OPERATE
- Check if engine cranks with fully charged battery. If engine cranks with fully charged battery, check charging system. If engine does not crank with fully charged battery, go to next step.
- Check if battery voltage is supplied at "B" terminal. If battery voltage is supplied at "B" terminal, go to next step. If battery voltage is NOT supplied at "B" terminal, check wiring harness.
- Check if battery voltage is supplied at "S" terminal with clutch pedal depressed (M/T), car in park (A/T), and ignition switch in START position. If battery voltage is supplied at "S" terminal, replace starter unit. See «STARTER»(ref-164133-S30857407152004072200000) under REMOVAL & INSTALLATION. If battery voltage is NOT supplied at "S" terminal, check transaxle range switch, ignition switch, and wiring harness.
WILL NOT CRANK-STARTER MOTOR SPINS
Check if drive pinion is pulled out while cranking (click heard when pulled out.) If drive pinion is pulled out while cranking, remove starter and check flywheel ring gear teeth and starter drive pinion teeth. If drive pinion is NOT pulled out while cranking, replace starter unit. See STARTER under REMOVAL & INSTALLATION.
CRANKS SLOWLY
- Check if engine cranks normally when battery is fully charged. If engine cranks normally when battery is fully charged, then check charging system. See appropriate GENERATORS & REGULATORS article. If engine does not crank when battery is fully charged, go to next step.
- Check starter cable connection for looseness and corrosion. If starter cable connection is loose or has corrosion, repair or replace connection. If starter cable connection is not loose or corroded, check for seized motor armature. Repair or replace as necessary.
